SEDIMENT-COLLECTING DEVICE AND WATER-INLET VALVE FOR KITCHEN-BOILERS.

Specification of Letters Patent.

Application 'filed August 13, 1915.. Serial No. 45,383.

To all whom it may concern Be it known that I, JOHN F. POLMANN, a citizen of the United States, and a resident of East Rutherford, in the county of Bergen and State of New Jersey, have invented a new and Improved Sediment-Collecting Device and VVater-Inlet Valve for Kitchen-Boilers, of which the following is a full, clear, and exact description.

This invention relates to a valve device for use in connection with kitchen and other boilers for preventing the circulation of sediment through the boiler system and for enabling the collected sediment to 'be drawn off from time to time in a simple,- convenient and eflicacious manner.

The invention has for its general objects to provide a comparatively simple, inexpensive and reliable device of the character referred to of such design that it can be applied to boilers already in use without any change in the latter or the piping system, the device including separate ports, one being normally closed and located directly at the bottom of the boiler and the other being normally open and located at a suitable level above the bottom of the boiler, so that sediment can collect at a point below the nor.- mally open port, and by means of a movable element or valve the normally closed port can be opened andthe normally open port closed, so that the sediment can be drawn off through the hot water service pipe when a faucet therein is opened and left open until the water runs clear, which indicates that the sediment has been removed.

With such objects in view, andv others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention, and wherein similar characters of reference indicate corresponding parts in all the views, Figure 1 is a vertical section of a kitchen boiler with the sediment collecting and water inlet valve applied thereto; Fig. 2 is an enlarged sectional view of the device, showing the valve thereof in normal position; Fig. 3 is a perspective view of the ported valve inclosed tubular member forming the portion ofthe device located within the boiler; Fig. 4 is a horizontal section on the line 4%, Fig. 2; F ig, 5 is a detail view of the lower end of the valve stem or rod; and Fig. 6 is a section on the line 6-6, Fig. 5.

In the present instance the invention is shown in connection with an ordinary kitchen boiler, but it is to be understood that it may be used with other devices where it is desirable to collect sediment and draw it oft from time to time.

Referring to the drawing, A designates a boiler which at its bottom is provided with the usual threaded'opening 1, into which the sediment collecting and water inlet device B is inserted. The hot water outlet or service pipe a is connected with the top of the boiler and the opening 5 to which the inlet pipe is usually connected is closed by a plug 0. The pipe (11 connects the boiler with a water back (not shown), and the hot water from the latter flows into the boiler through the usual pipe e. This device B comprises a casting or other suitable body 2 having a horizontal arm 3 connected with the pipe (Z which leads to a waterback or other heater. The vertical arm 6 of the body 2 is provided with an upwardly extending tube 7 having its lower end screwed into or otherwise fastenedto the body 2, and in this tube 7 are upper and lower ports 8 and 9. Rotatably mounted and surrounding this hollow extension '7 of the body 2 is a valve 10 of tubular form, which has its lower end 11 bearing on the upper end 12 of the body 2, and the top of the valve 10 is provided with a head 12 secured by a pin or equivalentmeans 13. In this head is threaded or otherwise secured the upper end 14 of a valve stem'15 which extends vertically the full length of the device, and on the lower end of the stem which extends out of the body 2 is an operating handle or equivalent means 16. The valve 10 has ports 8 and 9 50 disposed that when one registers with its complementary port in the tube 7, the other will be out of register with its complementary port. and by turning the valve stem through the medium of the handle 16, the valve can be adjusted so that either the upper port 8 or the lower port 9 will be opened. The rotary movement of the valve is limited so that at the limit or" its movement in either direction the upper or lower ports will be open. This limiting means comprises a stop scribed the principle of operation,

formed by the pin 13, and on the tube 7 are spaced shoulders or abutments 18 and 19 formed by the ends of a slot S, Fig. 3, with either of which abutments the stop 13 is adapted to engage. \Vhere the valve stem 15 passes out of the body 2 there is formed an extension 20 that is externally threaded to receive the gland nut 21, which latter contains packing material 22, so that a watertight joint is provided. The stem 15 is provided with a collar 23 which engages a shoulder 2% in the extension 20, whereby longitudinal movement of the valve stem 15' is prevented. This collar 23 is in the form of a ring set into a groove 25 in the valve stem.

The cold water enters the boiler A through the-device B, and for this purpose the body 2 of the device B has a downwardly and laterally extending nipple orhranch 26 to which the water supply pipe 27 is connected. \Vhenever a valve in the hot water system is opened to draw off hot water, water flows into the boiler A through the pipe 27, device B, and out through the upper ports of the latter. WVhen, however, no water is flowing out of the boiler through the outlet pipe a, water circulates from the lower part of the boiler downwardly through the device B, through the pipe 03, waterback and return pipe 6. It will be noted that the water below the level of the upper ports in the device B is always in a quiescent state as long as the lower ports are closed, so as to be conducive to the settling of sediment. IVhen it is desired to clean out the boiler the valve 10 is rotated so as to open the lower ports and close the upper ports, and when a faucet is opened in the hot water supply pipe (1., cold water will rush into the boiler through the lower ports of the device B and thereby agitate the sediment in the bottom of the boiler. This causes the sediment to flow off with the water through the outlet pipe at which is left open for ten or fifteen minutes more or less until the water runs clear. This indicates that the sediment has been drawn off and the device B can now be restored to normal position so that water can flow into'and out of the device B through the upper ports thereof.

From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood bythose skilled in the art to which the. invention appertains, and while I have detogether with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes maybe made when desired as fall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
